Swimmer Spyros Gianniotis was born in Liverpool, England, but he will represent Greece in the upcoming London Olympics. At 32, he is the 10-kilometer open-water world champion, and one of Greece's best hopes for a medal in London. He's on a team of Olympians whose training budget has been drastically reduced by austerity measures and the economic crisis.

On a recent morning, Gianniotis' training included three hours of laps in an outdoor Olympic-sized pool in central Athens. The lean, freckled marathon swimmer glides to the end of the pool.

Rep. Thaddeus McCotter, R-Mich., is facing the daunting prospect of running a write-in campaign to get re-elected this year, as his campaign fell far short of the number of petition signatures he needs to qualify for the August primary ballot.

Compounding McCotter's troubles: It appears election fraud may have played a part in the failure.

What snarky headline writer could resist a story about "hot tuna?" Or how about "tuna meltdown?"

Really, it seems just plain daffy to ignore a new study that says some Pacific bluefin tuna picked up traces of radioactive material from the Fukushima nuclear disaster last year and brought it across the Pacific Ocean.

A shortage of Adderall began last year, sending millions of people with attention deficit/hyperactivity disorder and narcolepsy on perpetual wild goose chases to find drugstores with the pills they need to stay alert and focused.

So it's not surprising that Adderall counterfeiters have seized a big marketing opportunity. What is surprising is their clumsiness.

In an interview with CNN, The Donald did not back down from his opinion that President Obama was not born in the United States.

CNN's Wolf Blitzer presented him with the overwhelming evidence that Obama was indeed born in Hawaii, but Donald Trump just raised his voice as he and Blitzer accused each other of sounding "ridiculous."

CNN calls it a "smackdown," and, indeed, it was a pretty contentious interview. Take a look:

On a recent Monday morning in Washington, D.C., a group of 3-year-old preschoolers bumbled their way into a circle, more or less, on the rug of their classroom. It was time to read.

The children sat cross-legged as their teacher, Mary-Lynn Goldstein, held high a book, Don't Let the Pigeon Drive the Bus. There was a short conversation about pigeons, then, for reasons that weren't entirely clear, cows; and then Goldstein began to read. She read as most teachers read, occasionally stopping to ask a question, point out a picture or make a comment about the story.

Congress is considering legislation allowing the government to search through Internet traffic for early warnings of cyberattacks. The bills are controversial — worries about government surveillance have led to protests online.

The government does have a tool that could calm fears about this kind of legislation — it just doesn't use it.

America is the land of opportunity — that's the bedrock of the American dream. Many expect each generation to do better than the last.

That dream of economic mobility is alive and well for Pam Krank and her husband, Brian McGee. The two are proud owners of The Credit Department Inc., a successful business in the Minneapolis suburb of Mendota Heights.

"Mostly manufacturing companies around the world will hire us to study their customers and tell them how much ... unsecured credit they should grant to each customer," Krank explains.

At the moment the polls close in Texas Tuesday evening, most media outlets and very likely even the Mitt Romney campaign will declare that he has secured enough delegates to win the Republican nomination for president.

For what it's worth, there are two problems with that statement. First, as a practical matter, Romney actually won the Republican nomination when the other candidates competing for delegates in the primaries and caucuses stopped doing so. That was weeks ago.

Saying that each one of the recipients has touched countless lives, President Obama presented 13 Presidential Medals of Freedom during a ceremony in the East Room of the White House today.

All of the people on the stage, Obama said, "are my heroes individually." He said that if it were not for John Doar, the Justice Department official who personally escorted University of Mississippi's first black student to campus, he would not be president.

It's a long, detailed look at how the president has "placed himself at the helm of a top secret 'nominations' process to designate terrorists for kill or capture, of which the capture part has become largely theoretical."

Yesterday, a short piece in a Japan-based foreign affairs magazine caused a lot of surprise: U.S. Special Forces have parachuted into North Korea "to spy on Pyongyang's extensive network of underground military facilities," The Diplomat reported.

The murder rate in New Orleans has consistently been well above the national average. But Mayor Mitch Landrieu is searching for answers to change that. He speaks with host Michel Martin about his five-step plan to lower the murder rate, his plans to reform the police department, and being mayor of a city in recovery.

I'm Michel Martin and this is TELL ME MORE from NPR News. Coming up, he's bringing new flavors from Latin America to places like Philadelphia, Atlantic City and Washington, D.C. We'll talk Nuevo Latino cuisine with the award-winning chef, Guillermo Pernot. That's in just a few minutes.

But first, we're going to continue our conversation with the mayor of New Orleans, Mitch Landrieu. We're talking about his administration's efforts to stop the killing in his city. Per capita, New Orleans has the highest murder rate in the country.

Word from the antivirus experts at Kaspersky Lab that "we've found what might be the most sophisticated cyber weapon yet unleashed," and that this Flame spyware is targeting Iran and some places in the Middle East, is getting lots of attention this morning:

Problem gambling isn't considered a true addiction in medical circles. But that may change as psychiatrists revise the diagnostic manual that spells out criteria for more than a dozen varieties of mental disorders.

Last week, the researchers who put out the Thomson Reuters/University of Michigan Survey of Consumers said their index rose in May to "its highest level since October 2007" — before the last recession began.

But when it comes to economics, there always seem to be an "on the other hand" moment coming — especially when the economy appears to be at a turning point.
